  Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings.

  An embodiment of the present invention will be described with reference to FIG. FIG. 1 is a diagram illustrating a configuration example of a radiation imaging system. As shown in FIG. 1, the radiation imaging system includes a radiation imaging apparatus 1 and an HIS (Hospital Information System) 11 that mainly manages the progress of the examination.

  In addition, the radiation imaging system includes an RIS (Radiologic Information System) 12 that transmits an inspection order to the radiation imaging apparatus 1. Further, in the radiation imaging system, a PACS (Picture Archiving and Communication Systems) 13 for managing the radiation image and a printer 14 for printing out the radiation image are connected.

  The HIS 11 is a hospital management system, and includes a server that manages the progress of examinations and accounting information. When performing radiography, the operator inputs an inspection instruction from a terminal (input unit) of the HIS 11. Then, the HIS 11 transmits the request information to the radiation department of the hospital to which the radiation imaging has been requested. This request information is called an inspection order. The inspection order includes a requesting department name, an inspection ID, an inspection item, personal data on a subject (subject), and the like.

  When receiving the examination order by the RIS 12, the radiology department adds imaging information (imaging part information, imaging direction information, procedure information, and the like) regarding the radiography to the examination order as an imaging protocol, and transmits it to the radiation imaging apparatus 1. The radiation imaging apparatus 1 performs radiation imaging according to the received inspection order. The radiation imaging apparatus 1 acquires a captured radiation image, generates inspection information in which the radiation image is associated with the inspection order, and outputs the generated inspection information together with the radiation image.

  The PACS 13 is a server that manages radiation images. The high-definition monitor connected to the PACS 13 performs a radiographic image inspection operation and detailed post-processing and diagnosis operations. Thus, the radiation image acquired by the radiation imaging apparatus 1 is transmitted to the PACS 13.

  In addition, information on the inspection performed by the radiation imaging apparatus 1 (image ID, imaging date and time, etc.) is transmitted to the HIS 11. The execution information transmitted to the HIS 11 is used not only for the management of the progress of the inspection but also for the accounting process after the inspection.

  The radiation imaging apparatus 1, the HIS 11, the RIS 12, the PACS 13, and the printer 14 are connected via a network 15 including, for example, a LAN (Local Area Network) or a WAN (Wide Area Network).

  Each of these devices includes one or more computers. The computer is provided with, for example, main control means such as a CPU and storage means such as a ROM (Read Only Memory) and a RAM (Random Access Memory). Further, the computer may be provided with communication means such as a network card, input / output means such as a keyboard, a display, and a touch panel. These components are electrically connected by a bus or the like, and are controlled by the main control unit executing a program stored in the storage unit.

  As shown in FIG. 1, a radiation imaging apparatus 1 that performs radiation imaging is installed in an imaging room 100. Further, in the imaging room 100, a radiation generating device 4 that generates radiation, a radiation detecting device 7 that captures a radiation image by detecting radiation transmitted through the subject 10, and an imaging device that holds the radiation detecting device 7 A table 6 is provided.

  The radiation imaging apparatus 1 includes a display unit 2 that displays a radiation image and various information, an operation unit 3 that is operated by an operator, and a control unit 5 that controls each component.

  The radiation generation device 4 sets the imaging conditions of radiation in the radiation generation unit 8 and controls the generation of radiation from the radiation generation unit 8. The radiation generator 8 functions as a radiation source that generates radiation. The radiation generating unit 8 is realized by, for example, a radiation tube (X-ray tube), and irradiates a subject 10 (for example, a specific part of the subject) with radiation.

  The radiation generator 8 can irradiate a desired irradiation range with radiation. A stop (not shown) for shielding radiation is installed on the irradiation surface of the radiation generator 8. The operator can adjust the irradiation range of the radiation emitted from the radiation generator 8 by controlling the aperture that shields the radiation.

  The radiation imaging system includes a radiation detection device 7 that detects radiation emitted from the radiation generator 8. The radiation detection device 7 detects radiation transmitted through the subject 10 and outputs a radiation image corresponding to the radiation. Note that a radiation image is also referred to as radiation data.

  Specifically, the radiation detection device 7 detects radiation transmitted through the subject 10 as electric charge corresponding to the amount of transmitted radiation. For example, the radiation detection device 7 uses a direct conversion sensor that directly converts radiation such as a-Se that converts radiation into electric charge, a scintillator such as CsI, and a photoelectric conversion element such as a-Si. Used indirect type sensor is used.

  The radiation detection device 7 is a portable cassette-type radiation detection device, and is carried together with the radiation generation device 4 to an imaging room 100 where an inspection is performed. Radiation imaging is performed by using radiation detection devices having different sizes according to the size of the subject and the imaging region. Here, the radiation detection device 7 installed on the imaging table 6 is used for radiation imaging.

  The radiation detection device 7 generates a radiation image by A / D-converting the detected electric charge, and accumulates the radiation image in a storage unit (not shown). The radiation detection device 7 can add image information (image ID, imaging date and time, and transfer status of the radiation image) to the radiation image, and transfer the radiation image to the radiation imaging device 1 together with the radiation image.

  The display unit 2 is realized by, for example, a liquid crystal display or the like, and displays various kinds of information to an operator (for example, an imaging technician or a doctor). The operation unit 3 includes, for example, a mouse and operation icons, and inputs various instructions from an operator to each component. Note that the display unit 2 and the operation unit 3 may be realized as a touch panel in which they are integrated.

  The control unit 5 of the radiation imaging apparatus 1 is connected to the radiation detection apparatus 7 via a wireless LAN. A radiation image, a control signal, and the like are transmitted and received between the control unit 5 and the radiation detection device 7. That is, the radiation image stored in the radiation detection device 7 by the radiation imaging is output (transferred) to the control unit 5 via the wireless LAN.

  The radiation imaging apparatus 1 includes a control unit 5 that performs image processing on a radiation image output from the radiation detection apparatus 7 and generates an image. The control unit 5 has an application function that operates on a computer. The control unit 5 controls the operation of the radiation detection device 7, outputs a radiation image to the display unit 2, and outputs a graphical user interface (GUI).

  The control unit 5 of the radiation imaging system of the present invention will be described in detail with reference to FIG. The control unit 5 includes an imaging control unit 21 that performs imaging control of the radiation detection device 7, an image processing unit 22 that performs image processing on a radiation image obtained by imaging, a radiation image output from the radiation detection device 7, A storage unit 23 for storing various information such as an order, a shooting protocol, and a shooting method. In addition, the control unit 5 determines whether the storage unit 23 has the inspection management unit 24 that manages the inspection information in which the radiation image and the inspection order are associated, and the imaging method that is the same as the imaging method of the imaging protocol associated with the inspection order A determination unit 25 that determines whether or not the determination is made, and a determination condition setting unit 26 that sets determination conditions in the determination unit 25 are provided. The determination unit 25 determines whether the imaging method of the imaging protocol associated with the inspection order matches one of the plurality of imaging methods stored in the storage unit 23.

  The storage unit 23 stores examination information managed by the examination management unit 24, an imaging protocol, an imaging method, a radiation image output from the radiation detection device 7, and various information necessary for inspection management. Further, the storage unit 23 stores an imaging protocol associated with the inspection order together with identification information for identifying the imaging protocol.

  The inspection management unit 24 manages an imaging protocol in which an imaging method, imaging conditions, image processing conditions, and the like, which are associated with the inspection order, are defined. For example, when generating examination information in the radiation imaging apparatus 1, the examination management unit 24 can create new examination information by associating the subject information input from the operation unit 3 with an imaging protocol. On the other hand, when an examination is requested from the RIS 12, the examination management unit 24 extracts the imaging protocol stored in the storage unit 23 using the received identification information of the imaging protocol associated with the inspection order. The extracted imaging protocol is associated with the inspection order, and new inspection information is created. The newly created inspection information is stored in the storage unit 23.

  The imaging control unit 21 transmits a transfer request signal that requires transfer of the radiation image stored in the radiation detection device 7 to the radiation detection device 7 and receives the radiation image from the radiation detection device 7. The imaging control unit 21 manages the received radiation image together with radiation detection device information on the radiation detection device 7. Further, the imaging control unit 21 associates the radiographic image with the inspection information and the imaging protocol managed by the inspection management unit 24.

  The image processing unit 22 performs image processing on the radiation image using the imaging protocol and the image information obtained from the imaging control unit 21. The radiation image subjected to the image processing is displayed on the display unit 2. The image processing unit 22 performs image processing for adjusting the image itself such as luminance and contrast. Furthermore, the image processing unit 22 can also perform processing such as clipping and annotation on the adjusted radiation image.

  The determination unit 25 determines whether or not the imaging protocol executed by the radiation detection device 7 is associated with the inspection order and belongs to the same imaging method group as the imaging protocol stored in the storage unit 23. The imaging protocol stored in the storage unit 23 is managed by the examination management unit 24. The photographing protocol stored in the storage unit 23 is, for example, the photographing protocol that was most recently photographed. In other words, the determination unit 25 determines whether the imaging protocol of the radiation imaging performed by the radiation detection device 7 belongs to the same imaging method group as the imaging protocol managed by the inspection management unit 24, which is associated with the inspection order. I do.

  The imaging protocol includes an imaging method (an imaging part, an imaging direction, an imaging posture, and the like) and imaging conditions (tube voltage, tube current, irradiation time, and the like) set by the radiation generator 4. The shooting method and the shooting conditions are stored as a shooting protocol. The determination unit 25 compares the imaging method of the imaging protocol of radiation imaging performed by the radiation detection device 7 with the imaging method of a plurality of imaging protocols in the same inspection, and associates the imaging method with the imaging method group. It can also be determined whether they belong. In other words, the determination unit 25 determines whether or not the imaging method of the imaging protocol of the radiation imaging performed by the radiation detection apparatus 7 is the same as the imaging method of the imaging protocol in the same inspection, which is associated with the inspection order. .

  FIG. 3 is a diagram illustrating the determination of the same imaging method group by the determination unit 25 of the present invention. FIG. 3A shows an imaging protocol table stored in the storage unit 23. The shooting protocol table associates various information such as a shooting method, shooting conditions, and image processing conditions with the shooting protocol. The imaging protocol table holds identification information (ID) of the imaging protocol and an imaging protocol name. The shooting protocol table holds identification information (ID) for extracting a shooting method, a shooting condition, and an image processing condition. In the shooting protocol table, if the shooting method ID of the shooting protocol is the same, the shooting method is the same. For example, in FIG. 3A, the shooting method ID is T1 when the shooting protocol IDs are P1 and P3, which are the same. Therefore, the shooting methods in the shooting protocols P1 and P3 are the same shooting method.

  In the shooting protocol table, if the shooting condition ID of the shooting protocol is the same, the shooting conditions are the same. For example, in FIG. 3A, the shooting condition ID is EX1 for shooting protocol IDs P1 to P3, which are the same. Therefore, the shooting conditions in the shooting protocols P1 to P3 are the same shooting conditions. Similarly, the shooting condition ID is EX2 when the shooting protocol IDs are P4 and P5, which are the same. Therefore, the shooting conditions in the shooting protocols P4 and P5 are the same shooting conditions.

  In the shooting protocol table, if the image processing condition ID of the shooting protocol is the same, the image processing conditions are the same. For example, in FIG. 3A, the image processing condition IDs for the shooting protocol IDs P1 and P6 are IP1, which is the same. Therefore, the image processing conditions in the imaging protocols P1 and P6 are the same image processing conditions. Similarly, the image processing condition IDs for the shooting protocol IDs P2 and P7 are IP2, which are the same. Therefore, the image processing conditions in the imaging protocols P2 and P7 are the same image processing conditions.

  FIG. 3B shows a shooting method table in which the shooting condition IDs of the shooting protocol shown in FIG. 3A are classified. The shooting method table holds the ID of the shooting method. Further, it stores imaging information of the subject in radiation imaging such as an imaging region, an imaging direction, and an imaging posture. Note that the distance between the radiation generator 8 and the radiation detection device 7, the body thickness of the subject 10, and the like may be stored as information on the imaging method.

  In the imaging method ID of the imaging method table, if at least the imaging part and the imaging direction are the same, the same imaging method is used. For example, in FIG. 3B, the imaging part of the imaging method with the imaging method IDs T1 and T9 is the chest, and the imaging direction is Poster / Anterior, which is the same. Therefore, the imaging methods with the imaging method IDs T1 and T9 are the same imaging method.

  Then, the determination unit 25 determines whether or not there is an imaging protocol associated with the inspection order and belonging to the same imaging method group as the imaging protocol performed by the radiation detection device 7 based on the imaging protocol table.

  As shown in FIG. 3A, in the shooting protocol table, if the shooting method ID of the shooting protocol is the same, the shooting method is the same. The determination unit 25 determines whether there is an imaging protocol associated with the inspection order and belonging to the same imaging method group as the imaging protocol performed by the radiation detection device 7 based on the imaging protocol table. For example, in FIG. 3A, the imaging protocol P1 of the chest PA and the imaging protocol P3 of the pneumoconiosis have the same imaging method ID T1 and are the same. The same imaging method ID indicates an imaging protocol for imaging the same part from the same direction.

  The pneumoconiosis process, which is the image process of the pneumoconiosis imaging protocol P3, is a process of generating a radiographic image by applying image processing predetermined for pneumoconiosis separately from a radiographic image to which normal image processing is applied. Specifically, the pneumoconiosis processing differs in image processing parameters relating to gradation conversion, luminance, contrast, edge enhancement, and noise removal for each frequency component, as compared with normal image processing.

  Here, the imaging protocol table shown in FIG. 3A is an imaging protocol stored in the storage unit 23 and managed by the inspection management unit 24, or an imaging protocol associated with an inspection order in the same inspection. The determination unit 25 determines whether the imaging method of the imaging protocol associated with the subject's examination order matches the imaging method in the imaging protocol table. That is, the determination unit 25 determines whether the imaging protocol associated with the examination order of the subject belongs to the same imaging method group in the imaging protocol table.

  When the imaging method included in the examination order of the subject matches the imaging method in the imaging protocol table, the image processing unit 22 performs the same image processing as that of the imaging method in the imaging protocol table on the radiation image. To generate a radiation image.

  For example, if the imaging method of the imaging protocol associated with the new inspection order is T1, the determination unit 25 determines that the imaging method of the imaging protocol associated with the inspection order of the subject matches the imaging method T1 in the imaging protocol table. It is determined. The image processing unit 22 performs image processing (image processing for the chest PA, processing for pneumoconiosis) of the imaging method in the imaging protocol table on the radiation image, and generates each radiation image.

  Here, as in the imaging method T2 and the imaging method T9 shown in FIG. 3B, for example, the same imaging method is determined even if the imaging posture is not the same. That is, the same imaging method is used at least when the imaging part and the imaging direction are the same. Therefore, the determination condition setting unit 26 can set the determination condition in the determination unit 25. The determination condition setting unit 26 can add the imaging posture to the imaging region and the imaging direction that are the determination conditions in the determination unit 25. Specifically, the determination unit 25 determines that the imaging method is the same if the imaging protocol, the imaging direction, and the imaging posture of the imaging protocol associated with the examination order of the subject are the same in the imaging protocol table. . When the imaging part, the imaging direction, and the imaging posture of the imaging protocol associated with the examination order of the subject match the imaging part, the imaging direction, and the imaging posture in the imaging protocol table, the image processing unit 22 performs imaging on the radiation image. The same image processing as that of the imaging method in the protocol table is performed to generate a radiation image.

  FIG. 3C shows a photographing condition table stored in the storage unit 23. The shooting condition table holds identification information (ID) of the shooting condition. Further, it stores imaging conditions relating to radiation generated by the radiation generator 4, such as EIT (Exposure Index Target). The determination unit 25 determines that the imaging method is the same if the imaging protocol, the imaging direction, and the imaging conditions of the imaging protocol associated with the examination order of the subject are the same in the imaging protocol table. If the imaging part, the imaging direction, and the imaging condition of the imaging protocol associated with the subject's examination order match the imaging part, the imaging direction, and the imaging condition in the imaging protocol table, the image processing unit 22 performs imaging on the radiation image. The same image processing as that of the imaging method in the protocol table is performed to generate a radiation image.

  Here, as shown in FIG. 3A, the imaging protocol P1 of the chest PA and the imaging protocol P3 of the pneumoconiosis have the same imaging condition ID in addition to the imaging method ID. The fact that the imaging method ID and the imaging condition ID are the same indicates that the same imaging method and the same radiation are irradiated from the radiation generator 4 to perform imaging. The determination unit 25 determines that these imaging protocols belong to the same imaging method group. FIG. 3C illustrates the imaging conditions such as the tube current, the tube voltage, the irradiation time, and the EIT, but these parameters are not necessarily required. If the tube current, the tube voltage, and the irradiation time of the radiation generator 4 match, the determination unit 25 can also determine the same imaging condition. If the voltages match, it can be determined that the same imaging condition is used. The determination condition setting unit 26 can also set the determination conditions regarding the photographing conditions in the determination unit 25. Then, if the imaging conditions of the imaging protocol associated with the examination order of the subject are the same in the imaging condition table, the determination unit 25 determines that the imaging conditions are the same.

  FIG. 3D shows an image processing condition table stored in the storage unit 23. The image processing condition table holds identification information (ID) of the image processing condition. Further, image processing conditions such as parameters of image processing such as luminance, contrast, and enhancement processing to be performed on a captured image are stored. The determination condition setting unit 26 can also add image processing conditions to the imaging region and the imaging direction, which are the determination conditions in the determination unit 25.

  As described above, the determination condition setting unit 26 can arbitrarily set the determination condition in the determination unit 25. In addition to the imaging region and the imaging direction that are necessary for the determination unit 25 to determine the imaging method, the determination condition Parameters (photographing posture, photographing conditions, etc.) can be set.

  FIG. 4 shows a display mode of the display unit 2 of the radiation imaging system of the present invention. FIG. 4 shows an imaging screen in which an examination to be performed is specified, and an instruction to start the examination is received and displayed on the display unit 2. As shown in FIG. 4, the display unit 2 includes a captured image display area 110, subject information 104, examination information 105, and an imaging protocol icon 109 corresponding to the imaging protocol (a chest PA icon 109 a and a pneumoconiosis icon 109 b). , The chest LL icon 109c) and the image processing setting area 112 are displayed. The subject information 104 is subject information such as a subject name, a subject ID, a date of birth, and gender.

  When the photographing screen is displayed, the photographing protocol icon 109a arranged at the top of the examination information 105 is selected by default. Along with this, the control unit 5 of the radiation imaging apparatus 1 transmits the imaging conditions (tube voltage, tube current, irradiation time, etc.) set in accordance with the imaging protocol to the radiation generator 4. Further, the control unit 5 controls the radiation detection device 7 according to the imaging method information to prepare for imaging.

  When the preparation for imaging is completed, the radiation imaging apparatus 1 transitions to an imaging enabled state. At this time, in the message area 111, a “Ready message” indicating that the photographing is possible is displayed.

  At this time, based on the determination result of the determination unit 25, the display unit 2 highlights the icon of the imaging protocol belonging to the same imaging method group as the imaging protocol in the imaging enabled state. Specifically, the display unit 2 highlights the pneumoconiosis icon 109b belonging to the same imaging method group as the chest PA icon 109a in the image capturing enabled state. Icon highlighting is a display in which the display mode of an icon (for example, icon color, frame, etc.) changes and can be distinguished from other icons. The operator can understand that there is a shooting protocol belonging to the same shooting method group as the shooting protocol that has become ready for shooting.

  Subsequently, the operator confirms the imaging method, sets the imaging, and positions the subject. When a series of imaging preparations is completed, the operator refers to the message area 111 to confirm that the imaging is possible, and then presses a radiation irradiation switch (not shown) of the radiation generator 4 that generates radiation. Then, the radiation imaging control device 1 causes the radiation generator 8 to irradiate the subject with radiation toward the subject (an imaging part of the subject), and causes the radiation detection device 7 to detect the radiation transmitted through the subject. As a result, a radiographic image is captured.

  When the imaging is completed, the control unit 5 of the radiation imaging apparatus 1 acquires a captured image from the radiation detection device 7, and the image processing unit 22 performs image processing on the radiation image based on predetermined image processing conditions. . The predetermined image processing conditions are defined in advance corresponding to the shooting method. If there is an imaging protocol belonging to the same imaging method group as the imaging protocol whose imaging has been completed in the same examination, the image processing unit 22 performs image processing based on the above-described predetermined image processing conditions also for the imaging protocol. I do.

  By operating the icon of the photographed protocol of the photographed image, the image displayed in the photographed image display area 110 is switched. When the imaging is completed, a radiographic image of the chest PA protocol corresponding to the chest PA icon 109a is displayed in the captured image display area 110. By operating the pneumoconiosis icon 109b, the operator can display a radiological image of the pneumoconiosis protocol.

  When the image processing ends, the radiation imaging apparatus 1 displays the captured image on which the image processing has been performed in the captured image display area 110. When the operator wants to change the contrast or the like of the captured image, the operator operates icons such as contrast and brightness provided in the image processing setting area 112.

  Similarly, when it is desired to change the cutout area of the output image, the user operates the cutout icon 122 and the cutout frame 126 to specify a desired cutout area. When adding a character string serving as diagnostic information, the user operates the annotation icon 123 or the like to superimpose a character string as indicated by the annotation 127 on the image. If the orientation of the radiation image is not suitable for diagnosis, geometric conversion is performed using the rotation icon 120, the reverse icon 121, and the like. If the radiographic image is not suitable for diagnosis, re-imaging and image-failure setting are performed using the re-imaging icon 124, the failure icon 125, and the like. As described above, the operator can perform additional image editing on the radiation image displayed in the captured image display area 110.

  The operator repeats the above-described procedure to photograph the icons of all the photographing protocols in the photographing information display area 105. When all imaging is completed, the operator presses the examination end icon 113. Thus, a series of inspections is completed.

  Next, the procedure of the shooting and image processing application processing will be described with reference to the flowchart shown in FIG.

  First, the operator creates an inspection order to be executed from the operation unit 3 and instructs the start of the inspection. When the inspection order is received from the RIS 12, a list is displayed on the display unit 2, and the operator selects from the list. (S101)

  The control unit 5 displays the shooting screen shown in FIG. The operator operates the photographing protocol icon 109 to specify the photographing protocol. The icon of the leading imaging protocol may be automatically designated in accordance with the examination start instruction. (S102)

  The operator installs the radiation generator 4 and the radiation detector 7 on the subject 10 and prepares for imaging. When the preparation for imaging is completed, the radiation irradiation switch of the radiation generator 4 for generating radiation is pressed down, and the radiation is emitted toward the radiation detector 7. The radiation detecting device 7 that has detected the radiation generates a radiation image. (S103)

  The imaging control unit 21 receives the imaging execution notification from the radiation detection device 7 and receives the generated radiation image. The received radiation image is stored in the storage unit 23 in association with the imaging protocol performed by the examination management unit 24. (S104)

  The imaging control unit 21 further causes the image processing unit 22 to perform image processing on the received radiation image. The image processing conditions used at this time are set in advance for the shooting protocol as shown in, for example, FIGS. 3A and 3D. (S105) The processed radiation image is displayed on the display unit 2. This completes a series of flows for shooting in S103. (S106)

  Here, the determination unit 25 determines whether the imaging protocol performed by the radiation detection device 7 belongs to the same imaging method group as the imaging protocol stored in the storage unit 23, and determines whether the imaging protocol is in the same examination being performed. It is determined whether or not there is a shooting protocol belonging to the same shooting method group as the shooting protocol that performed the shooting. (S107)

  When there is an imaging protocol belonging to the same imaging method group, the examination management unit 24 associates the imaging protocol with the radiation image. Further, the image processing unit 22 performs image processing based on an imaging protocol belonging to the same imaging method group. (S108) The above processing is performed until there is no more imaging protocol belonging to the same imaging method group in the examination. The radiation image that has been subjected to the image processing can be displayed on the display unit 2 by instructing the icon 109 of the imaging protocol.

  As described above, according to the present embodiment, the storage unit 23 storing a plurality of imaging methods corresponding to the plurality of imaging protocols, and the plurality of imaging methods stored in the storage unit 23 according to the imaging protocol associated with the inspection order. A determining unit 25 that determines whether or not the imaging method matches one of the imaging methods; and if the determining unit 25 determines that the imaging method matches, the image processing of the imaging protocol corresponding to the matching imaging method is performed by the imaging protocol associated with the inspection order. And an image processing unit 22 applied to a radiation image captured based on the image data. Therefore, by appropriately performing image processing based on the imaging protocol associated with the inspection order, radiation imaging can be efficiently performed.

  Second Embodiment A radiation imaging system according to a second embodiment of the present invention will be described with reference to FIG. The first embodiment is an embodiment in which a radiation image obtained by the immediately preceding imaging is applied to an imaging protocol belonging to the same imaging method group. The second embodiment is an example in which a radiographic image of an imaging protocol of the same imaging method group captured in the past with a designated period is applied.

  The configuration of this embodiment is the same as that of the first embodiment, and a description thereof will not be repeated. Here, the operation of the radiation imaging system of the present invention will be described using the flowchart shown in FIG.

  First, the operator starts the inspection as in S101 of the first embodiment. (S201)

  Subsequently, the operator operates the photographing protocol icon 109 to designate the photographing protocol. (S202)
